Echo claims World First Mythic Sylvanas kill
The Echo guild from the Tarren Mill (EU) server is no stranger to World First races in World of Warcraft. However, Complexity Limit (US) has been the favourite in getting World First kills until Echo's sensational Mythic Sylvanas kill took place.
Echo came in with the World First Sanctum of Domination Mythic difficulty clear by taking Sylvanas to 45%, effectively downing the boss and claiming their spot as the top guild in the world...of Warcraft. The race was, without a doubt, one of the closest ever, with Complexity Limit getting the 45.4% the previous day.

The World First Mythic Sylvanas Windrunner kill happened just hours before the weekly reset.
After the reset, Complexity Limit managed to kill Sylvanas in one pull with a higher item level than their previous attempts, 13 hours after Echo, as they had to reclear all the bosses and get a few more items along the way.
That just goes to show that if Echo didn't kill Sylvanas on their final attempts before the weekly reset, Complexity Limit could have won the Sanctum of Domination World First race.
Check out Echo's celebration of the World First Mythic Sylvanas kill below.

Echo killed Mythic Sylvanas on their 169th attempt, while Complexity Limit had 213 pulls on the boss before their inevitable success.
It is also interesting to note that in the middle of the World First race, Blizzard implemented a hotfix for the Sylvanas fight, negating one of Echo's tactics in the process.

The hotfix in question added an enrage timer to the Mawforged Colossus which spawns during the second phase of the fight, in case you were wondering.
